RAPID: Hurricane Irene Storm Surge Sedimentation

这个快速项目将研究飓风艾琳在美国东海岸沿着沼泽地沉积的风暴潮沉积物。研究要解决的问题是：1。飓风艾琳风暴潮沉积的规模和区域分布是什么？2.飓风路径相对于海岸线的方向如何影响风暴潮沉积？3.飓风艾琳对沿海沼泽长期沉积的影响是什么？4.风暴潮沉积物是否保存在沼泽中？将使用的方法包括实地调查飓风艾琳的厚度、内陆渗透、体积、质量、空间分布和结构。的风暴潮存款。 此外，还将收集样本以确定背景沉积速率，从而比较飓风沉积及其在沿海沼泽演变中的总体作用，该项目旨在提高我们对飓风如何促进沿海沼泽形成的理解。这种高强度事件在这些沿海地貌特征的总体演变中的相对重要性仍然是辩论的主题。 该项目还将对古风暴学领域作出贡献，该领域对飓风袭击的重复间隔和相关的飓风风险进行评估。通过提供关于新飓风存款特征的信息，该项目将有助于限制对保存在地质记录中的过去事件的解释。

This RAPID project will study storm surge sediments deposited by Hurricane Irene in coastal marshes along the east coast of the United States. Questions to be addressed by the study are:1. What is the magnitude and regional distribution of Hurricane Irene storm surge sedimentation?2. How does the orientation of the hurricane track in relation to the coastline affect storm surgesedimentation?3. What is the contribution of Hurricane Irene to long-term sedimentation in coastal marshes?4. Are the storm surge deposits preserved in marshes?Methods to be used include field surveys of the thickness, inland penetration, volume, mass, spatial distribution and structures of Hurricane Irene?s storm surge deposit. In addition, samples will be collected to determine background sedimentation rates against which to compare the hurricane sedimentation and thus its overall role in coastal marsh evolution.This project aims to improve our understanding of how hurricanes contribute to the formation of coastal marshes. The relative importance of such high-magnitude events in the overall evolution of these coastal landscape features remains the subject of debate. The project will also contribute to the field of paleotempestology, which provides assessments of the recurrence interval of hurricane strikes and associated hurricane risk. By providing information on the characteristics of a fresh hurricane deposit, the project will help constrain interpretations of past events that are preserved in the geologic record.
